Shock propagation
WebIt then reviews in detail three main types of shocks: monetary, fiscal, and technology shocks. After surveying the literature, each section presents new estimates that compare and synthesize key parts of the literature. The penultimate section briefly summarizes a few additional shocks. Web15 Oct 2024 · The shock wave propagation presents an impedance, sensitive to porosity, but not to specific surface area. Such surprising phenomena are due to the similar sensitivities in density and stress variations to porosity or specific surface area.
